I was given a task that has me a tad bit overwhelmed. Our company is a 75 year old company but out network is only 2 to 3 years old. Our system admin wants the Spice Works inventory cleaned up since we are currently having our facilities fill out Inventory sheets. In the next few weeks I will be inputting this data from our facilities that are NOT within our network. My issue starts with the information within our network. I have plenty of SCAN errors (Authentication failed for user 'SW',Timeout waiting for WMI connection,Windows WMI port not open firewall problem?,Permission or firewall problem?) what exactly do all these mean and how do I correct this problem. I don't know where to begin with 63 scan errors. Is there a common practice to begin cleaning up these errors within the network.

I was able to fix a lot of the issue but now I have another question. With the authentication issues I went ahead and use the domain\user and pass credentials to test the scan error. It would fix it and then scan for other but it hasn't stopped for several hours. Is this normal? I do have about 60 scan errors but not all are authentications issue why is it taking so long.
